Problem conclusion

  • The Collector tool's code has been updated to better handle this
scenario (of an empty file being parsed first) so that a null-
pointer exception is not encountered.

The fix for this APAR is targeted for inclusion in fix pack
8.5.5.24 and 9.0.5.17. For more information, see 'Recommended
Updates for WebSphere Application Server':

Temporary fix

  • Make the file non-empty as a work-around.
